BOOT OR SHOE.

SPECIFICATION forming part of Letters Patent No. 475,858, dated May 31,1892..

Application filed May 5, 1891- gerial No. 391,699- (No model.)

To all whom it may concern.-

Be it known that I, GUSTAF E. HADLUND, a citizen of the United States,residing at Portland, in the county of Multnomah and State of Oregon,have invented certain new and useful Improvements in the Man u factureof Boots or Shoes by Means of a Combined Air-'lube and Counter-Brace;and I hereby declare that the following is a full, clear, and exactdescription of my invention, which will enable others skilled in the artto which it appertains to make and use the same.

My invention relates to improvements in boots or shoes; and the objectsare, first, to provide for the escape of heat from the shoe caused bythe foot, and thus ventilate the sole without destroying the flexibilityor injuring the appearance of the boot or shoe, and, secondly, toprovide a shoe or boot which will be quite lighter and the soles ofwhich will be drier than boots or shoes made in the ordinary manner.

With these ends in view my invention consists in the peculiarconstruction and arrangement of parts, as will be hereinafter describedand claimed.

In the accompanying drawings, Figure 1 is a bottom plan view of a shoehaving its lower or outer sole removed constructed in accordance with myinvention. Fig. 2 is a similar view of the sole of the shoe, the piece Kand pads 0 being removed. Fig. 3 is a vertical sectional view of theshoe. Fig. 4 is a detail view of one of the corrugated pads, and Fig. 5is a detached detail view of the tube or conduit which provides for thepassage of air.

Like letters of reference denote corresponding parts in the severalfigures of the drawings, referring to which A designates a shoe of anydesired pattern and size, and B and C, respectively, the heel and solethereof.

E designates an angular or bent pipe or conduit, which is arrangedwithin the shoe at the rear or heel end thereof. The lower angular endor portion of the tube or conduit F, which lies above the heel B, isflattened and enlarged to form a funnel-shaped mouthpiece G, and saidtube extends rearwardly a short distance from the mouthpiece G and thenupwardly through the counter of the shoe, the outer end of said tubebeing on a line with the vamp or seam at the top of the counter. Theenlarged portion G of the tube F extends a short distance beyond theforward edge of the heel B, as shown in Fig. 2. By reference to Fig. 3it will be seen that the inner face of the upright portion of the tubeor conduit F is made flat and that such upright portion is curvedslightly in the direction of its length to conform to the shape of theheel. The tube F is preferably made of metal or other suitable material,and besides serving to conductair'into the interior of the shoe alsoserves to strengthen the counter of the shoe and prevent the same frombeing crushed by wear or bent to either side by reason of the uneventread of the person wearing the shoe.

To the inner sole H of the shoe, in advance of the enlarged inner end Gof the tube F, is

secured a strip K of leather or other suitable material. This piece Kextends from the forward enlarged end of the tube F to a point slightlybeyond or about the middle of the shoe; but it does not extend the'wholewidth of the shoe, so that channels or passages L are formed between thesides of said strip and the welt M of the shoe, thelowerorouter sole Oforming the bottom of the grooves or channels.

Between the outer sole 0 and the inner sole L, under the ball of thefoot, I arrange parallel corrugated pads or cushions 0, made of rubberor other suitable elastic material. The corrugated elastic pads O areseparated by a central space P, which, when the outer sole is inposition, forms an air channel or passage Q, which connects the twochannels or passages L. The passages L, P, and Q communicate with theinterior of the shoe through a series of perforations or punctures B, sothat air can pass through the tube F into the interior of the shoe.

The operation of my invention is as follows: As the wearer brings hisweight to bear on the ball of the foot the air between the corrugationson the elastic pads O, which has become heated from the .heat of thefoot, is forced out through the passages Q P L and up through the tubeF. 0001 air from the outside passes down said tube into the passagesarranged between the soles of the shoe and into all portions of the shoethrough the perforations or punctures R. It will thus be seen that Ihave provided a shoe, the interior of which will be kept cool and theappearance and flexibility of which will not be destroyed. The sole isnot weakened in my construction by having channels or grooves outtherein, and I am also enabled to materially decrease the weight of theshoe and at the same time strengthen it.

I am aware that changes in the form and proportion of parts and detailsof construction of the devices herein shown and described as anembodiment of my invention can be made Without departing from the spiritor sacrificing the advantages thereof, and I therefore reserve the rightto make such changes as fairly fall within the scope of my invention.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

In a boot or shoe, the combination, with a perforated insole, of theelastic corrugated pads O 0, arranged between the soles and spaced apartto form a central longitudinal passage P between themselves, said padsbeing arranged relatively to the sides of'the shoe to form the passagesQ, extending around the toe, the strip K, arranged between the soles inrear of the elastic pads and separated from the sides of the boot orshoe to form passages L, which communicate with the passages P Q, and anair-tube extending through the counter of the boot or shoe and havingits inner end G enlarged, flattened, and terminating at a point in rearof the strip K, substantially as described.
